CHARLES R. BARKER, OF CLEVELAND, OHIO, ASSIGNOR TO CLEVELAND WIRE SPRING C0., OF CLEVELAND, OHIO, A CORPORATION OF OI-IIO.

BED-SPRING FRAIVIE.

To all 'whom t may concern:

Be it known that I, CHARLES R. BAKKER, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Bed-Spring Frames, of which the following is a specilication.

This linvention relates to bed spring frames, and the general object of the invention is to provide a set of hangers for a bed frame capable of independent adjustment to permit the bed spring frame to be supported upon beds of different widths, and when so adjusted to be locked by a lever without the aid of tools or special implements, all substantially as hereinafter shown and described and more particularly pointed out in the claims.

In the drawing accompanying this application, Figure 1 is a top plan view of one end of a bed spring frame embodying two side rails of a bed, one of the hangers being unlocked and the other locked. Fig. 2 is an end elevation of the parts shown in Fig. 1, and showing in addition bed springs mounted on the frame. Fig. 3 is an enlarged view in section of one corner of a bed frame and a hanger locked in an adjusted position thereon, this view being taken on line 3 3, Fig. l. Fig. 4 is a sectional view of the frame and hanger unlocked, this view being taken on line H Fig. 1.

The bed spring frame as usually constructed is a rectangular angle-iron frame 2 having lattice work 3 upon which a plural number of helical bed springs 4 are mounted. This frame is provided at each corner with a fiat metal brace 5 riveted at its ends to the, end and side pieces and angularly related to said pieces. Heretofore, these braces have performed no other function than a bracing one, but I utilize these braces to provide a connection and support for a set of hookshaped hangers 6 having straight flat shanks 7, each shank being adapted to slidably engage the frame through an opening in the side pieces directly opposite each brace 5 and below the bottom face of the brace. Each hanger shank has a slot 8 through which a bolt or rivet 9 extends, preferably a rivet with a washer 10 at its lower end. The rivet is long enough to project through brace 5 and also through a flat bar or lever 11 rest- Specication of Letters Patent. Patented Dec. 16, 1919 Application filed April 30, 1919.

ing upon said brace, and the lower and upper ends of the rivet have round heads to hold the said parts together so that the hanger may slide and the lever turn freely. The short end of the leverhasadownwardlybent extremity l2 adapted to move in the arc of a circle within the angular corner space defined by the brace and the side and end pieces of the frame. In one position of the lever this bent extremity 12 projects beyond the side edge of the hanger shank and is disengaged therefrom to permit longitudinal adjustment of the hanger, see Figs. 1 and 4, but when the lever is turned on pivot member 9 the bent extremity 12 will ride over the straight edge and flat top of shank 7 and lock both the lever and hanger against independent movement, see Fig. 2. An effective binding or wedging action is obtained because the hanger shank will spring slightly under the pressure of the lever extremity when engaged intermediate the two points of rest or places of bearing furnished `by the rivet washer l0 and the frame 2 or if the lever is relatively the thinner part the lever itself will spring or flex in riding over the top of the shank. When mounted in a bed the weight of the frame places an additional locking strain on the parts. On the other hand, it is asimple matter t0 turn the levers and unlock the hangers, obviously without tools or effort other than by hand engagement with .the levers.

Finally, the use of the brace to secure the inner end of the hanger is not only a stable way of supporting the hanger but it also affords an effective way of locking the hanger adjustably upon the frame by the use of a single rivet and a short lever as shown and described.

What I claim is:

1. A bed spring frame having a slotted hanger, a pivoted locking lever for said hanger, and a fastening member for said hanger providing a pivot for said lever.

2. A bed spring frame having a corner brace, a slotted hanger slidably engaged with said frame and brace, a locking lever for the hanger and a pivot element for said lever extending through the slotted hanger and securing the lever and hanger together upon said brace.

3. A. bed spring frame, comprising side pieces and corner braces, hookshaped hangers slidably engaged with said side pieces and braces, and pivoted levers having bent extremities adapted to ride over and lock the said hangers immovably upon said frame.

4. A bed spring frame having a corner brace and a side piece With an opening therein opposite said brace, a hook-shaped hanger slidably engaged Within said opening having a shank slidably engaged With said brace, a lever pivotally supported upon said brace having a bent end adapted to ride upon said shank, and means adapted to secure said lever and hanger for independent moveinent upon said brace.

5. A bed spring frame having diagonal corner braces, slotted hangers projecting through said frame and slidably connected with said braces, and horizontally rotatable levers pivoted on said braces and having end portions in locking engagement on said hangers.
